MICA 

  Mica powder is a non-metallic mineral that contains multiple components, mainly SiO2, with a content generally around 49% and Al2O3 content around 30%. Mica powder has good elasticity and toughness. It is an excellent additive with characteristics such as insulation, high temperature resistance, acid and alkali resistance, corrosion resistance, and strong adhesion. It is widely used in industries such as electrical appliances, welding electrodes, rubber, plastics, paper making, paint, coatings, pigments, ceramics, cosmetics, new building materials, etc., with extremely wide applications. With the continuous development of science and technology, people have opened up new application fields.

Purpose:

1. Coating field：

Coating mica powder is a new functional green environmental protection filler. Its unique two-dimensional sheet like barrier, UV shielding, chemical structure stability and other functions effectively improve the permeability resistance, weather resistance, abrasion resistance and corrosion resistance of the coating film. In addition, it does not contain any Radioactive element, leading the trend of green environmental protection in the coating field. It is widely used in building exterior wall coatings, anti-corrosion coatings, powder coatings, high-temperature resistant coatings, insulation coatings, waterproof coatings, road sign coatings, radiation resistant coatings, and some special coatings, such as ship coatings, spacecraft thermal control coatings, and food container coatings.

2. Cosmetics field:

Cosmetic grade mica has a unique sheet-like structure, silky luster, and smooth texture, making the makeup powder as light and delicate as silk. The natural texture gives the skin an excellent affinity and crystal clear effect, giving cosmetics the characteristics of soft touch, soft luster, good affinity, and strong skin adhesion. It is the preferred high-end powder raw material in the cosmetics industry.

In addition, the crystal transparency of mica powder can maintain consistent intensity in makeup colors, and is also suitable for various shades of color. The unique nature of sericite can also increase its silky and flexible luster for cosmetic manufacturing. The products are widely used in powder, honey powder, eye shadow, liquid foundation, powder blusher, honey powder and many other fields.

3. Plastic field:

Plastic mica powder has the characteristics of high aspect ratio, high temperature resistance, acid and alkali resistance, and wear resistance, making it a natural functional powder filling material. The company selects high-quality mica ore and adopts a unique wet grinding peeling and purification process for processing. The mica layers have complete cleavage, preserving the unique high aspect to thickness ratio structure of mica (with an aspect to thickness ratio of over 100), making it have outstanding reinforcement effects in plastic products and endowing plastic products with excellent dimensional stability; The high temperature resistance characteristics of the product itself greatly improve the Vicat softening point of plastic thermal deformation thermometers, making it suitable for parts and products under high temperature conditions; Compared with glass fiber, mica has more characteristics such as smooth surface and no warping deformation of products. The products are widely used in PP, PA, PBT, PET and other plastic modification, functional master batch, Plastics engineering application and other fields.

4. Electronic field:

Mica powder is a new type of special functional filler that is suitable for the technical requirements of the copper clad plate industry. It can replace electronic grade silicon powder and endow the plate with ideal insulation, rigidity, low expansion rate, drilling processability, heat resistance, and process stability. Materials have complete chemical inertness and will not undergo cracking, metamorphism, or induced reactions even in high temperature and complex systems. They are particularly characterized by significantly improving drilling efficiency, drilling quality, and reducing drill bit wear, and are gradually becoming a popular material in the copper clad plate industry.

5. Rubber field:

Mica powder is an excellent rubber filling and reinforcing material, with a unique structure with a high aspect to thickness ratio that greatly enhances the reinforcing effect. Its excellent thin crystal shape greatly improves the airtightness, and its inherent polarization effect of mineral crystals and interlayer water molecule interference effect effectively shield ultraviolet, micro wave, and infrared rays, greatly improving the aging resistance of the product.

The application results of Beijing Rubber Research Institute, Henan Tire Factory, Sichuan Rubber Factory and other manufacturers in tire, tape, rubber plate, rubber tube, automotive rubber parts and other products have shown that sericite powder has good processing performance, which can replace 30-50% of semi reinforced or other coarse particle carbon black, or add a certain proportion of sericite powder to the original formula, which can maintain the performance of the rubber material unchanged and reduce product costs.

6. Refractory material field:

In the field of refractory materials, mica powder has stable main mineral content, moderate fire resistance, and stable insulation and physical and chemical properties; The mud has advantages such as good adhesion, non expansion, fast drying speed, good plasticity, and strong resistance to iron flow erosion.

7. Welding rod field:

Mica powder is a new type of electrode coating material in the field of welding materials. Its unique combination of chemical elements can improve arc stability, reduce splashing, improve the process performance of the electrode, and solve the problem of electrode coating cracking that often occurs during the production process of the electrode. When used in acidic electrodes such as E4303 and E4313, it is recommended to have a ratio of 3% to 5%, while also having certain elasticity and plasticity It can increase the smoothness of the electrode coating and its flowability in the powder cylinder, improve its pressure coating performance, replace titanium dioxide powder, and reduce the cost of the electrode.

8. Ceramic industry:

Mica ceramic is a special engineering material suitable for producing heat-resistant materials, insulation materials, high-temperature mechanical components, etc. It is widely used in the electrical and electronic industries. Mica ceramics are generally made by the crystallization glass method or sintering method. However, the flexural strength of mica ceramics produced by these two processes is not ideal enough. For example, the flexural strength of mica ceramics produced by glass crystallization method is generally only within the range of 100-140MPa, while the flexural strength of mica ceramics produced by sintering method is within the range of 120-130MPa. In order to significantly improve the strength characteristics of mica ceramics, a foreign company has developed an ingredient for producing high-strength mica ceramics through dedicated research and development.
